Trioxazolo[23]metacyclophane. Synthesis and Properties of a Novel [23]Metacyclophane Annelated with Three Oxazole Rings

Abstract

Abstract The title compound (6) was synthesized by the base-induced condensation of 3-(isocyanotosylmethyl)benzaldehyde as a new bifunctional reactant for the synthesis of [2n]metacyclophanes. The treatments of 6 with silver triflate in several molar ratios in THF at room temperature afforded only 2:1 silver triflate complex on the basis of the 1H NMR and the analytical data.
